It would definately be a woorthwhile upgrade to reduce weight generally, and unsprung weight most importantly.
I don't know if they're a direct replacement for DT125 wheels though, but would be interested to know this myself.
I have a DT200 swing arm (also alloy) to put on my bike, which I understand to be a direct fit, which would lead me to conclude (possibly wrongly) that DT200 wheels should fit a 125..... hopefully :)
aint workin sorry just type in dt200r wheel rim should bring up a few make shore you get the right ones coz i cant find the orignal ones that i was on about when i made the orignal post. sorry
I'm almost certain i have a alloy rim in my shed for a DTR, well it came off one and looks the same as one lol
DTR rims tend to rust away and when clean can look shiny where as this one tends to never even show a hint of rust and always looks merky rather then shiny
If anyone is remotely interested i'll get some pictures up..
here we go chaps just the rims on there own then you can have em powder coated http://www.ebay.co.uk/itm/YAMAHA-DT200WR-1992-Aluminium-Wheel-Rim-2-pcs-/190575508221?pt=Motorcycles_Parts_Accessories&hash=item2c5f2f7a
Thinking about this one myself hehe. Wonder how much it will cost to have em powder coated.
